i posted this earlier but here it is again.
the handy gadget is called the AVZ granule & link cutter and
sells for a hefty $250.00 (i think that is what it cost, it
might be slightly less). it is a nicely made tool but i feel it
is definitely overpriced. perhaps dave arens can be prodded to
make an alternative mechanism if you’re not in a hurry.
the number is: 707.762.5800. i suspect the fellow who makes the
machine does so in his spare time. he does call back, and
requires payment in advance.
